方法一:不改变原来对象
|
let item = {
name: "张三",
age: "18",
gender: "男",
};
console.log(item); // {age: "18",gender: "男",name: "张三"}
let { age, ...params } = item;
console.log(item); // {age: "18",gender: "男",name: "张三"}
console.log(typeof params.age); // undefined
console.log(params); // {gender: "男",name: "张三"}
|
二:直接改变对象
|
let item1 = {
name: "张三",
age: "18",
gender: "男",
};
console.log(item1); // {age: "18",gender: "男",name: "张三"}
delete item1.name;
console.log(typeof item1.name); // undefined
console.log(item1); // // {age: "18",gender: "男"}
